My objects "exploaded" instead of playing the animation
As it says in the comments under your video:
You have ALL of your cubes in one place. The must not intersect. So you &quot;forgot&quot; to move your cubes like he did in the video.
To move your cube, select it, then tap G then you can move it with your mouse.
Or better, press G X -&gt; then it only moves in x direction.
same with G Y or G Z.
